Yeah, a lot of peeps were having issues. It's very rare for me to get those black triangles now. The "flickering" you notice is actually a failure to render the texture for a split second. That too was a prevalent issue. With the 13.1's I have very few issues now. /Knocks on wood.

I thought so too at first. So what I did was to run the Heaven benchmark where I knew of several repeatable instances of the problem. I simply captured The video and frame by frame examined it till I found the culprit. It was a 1/10 of a second and the entire ship failed to render. It simply wasn't there for a tenth of a second.
